You have three (or so) options to break out of loops. Suppose you want to sum numbers until the total is greater than 1000. You try var sum = 0 for (i <- 0 to 1000) sum += i except you want to stop when (sum > 1000). What to do? There are several options. … Read more
Oh, I found it. You use last instead of break for my $entry (@array){ if ($string eq “text”){ last; } }
if is not a loop structure, so you cannot “break out of it”. You can, however, break out of the foreach by simply calling break. In your example it has the desired effect: $device = “wanted”; foreach($equipxml as $equip) { $current_device = $equip->xpath(“name”); if ( $current_device[0] == $device ) { // found a match in … Read more
No, don’t spoil it with a break. This is the last remaining stronghold for the use of goto.
Just like Perl, loop1: for (var i in set1) { loop2: for (var j in set2) { loop3: for (var k in set3) { break loop2; // breaks out of loop3 and loop2 } } } as defined in EMCA-262 section 12.12. [MDN Docs] Unlike C, these labels can only be used for continue and … Read more
My first instinct would be to refactor the nested loop into a function and use return to break out.
To break a $.each or $(selector).each loop, you have to return false in the loop callback. Returning true skips to the next iteration, equivalent to a continue in a normal loop. $.each(array, function(key, value) { if(value === “foo”) { return false; // breaks } }); // or $(selector).each(function() { if (condition) { return false; } … Read more
